LLT, thanks, you always make my day :)

Jason - "The first one is cool, but this one is even cooler" - I learned that from you, Kinny and several of the other artist on the board - try to make each piece better than the last one. Thanks

Mikel, I was thinking about you yesterday and woke up this morning to a comment from you
( :music: cue theme from the Twilight Zone :music: )
I sent the same question as a PM, I figured you would see one or the other.

I like Raku and would like to try some in my electric kiln (I assume that's possible, it's just harder to get the hot pieces out of the hot kiln) My question is how do you get a food safe, uncracked interior surface? I made up some test tiles and plates to experiment with some barrel firing and chemicals (copper chloride and iron oxide). With smoke firing, you can glaze and fire the inside first, then smoke the outside and still have it food safe. With Raku, seems like you can't do that. Even if you glaze the inside with a regular glaze (non-raku), it's going to crack from the thermal shock. If you re-fire the inside after Raku, you fire out the carbon on the outside??????? Hope I haven't asked you to reveal any trade secrets :)
